To all whom it may concern:

Be it known that I, JOSEPH LErLAIVE,citi- Zen of the French Republic,residing at St.- Etienne, Department of the Loire, in France, haveinvented certain new and useful Improvements in Means for Filling theMolds of Briqueting-Presses, of which the following is a specification.

The invention relates to double compression agglomerating presses of theCouffinhal type, such as is described for instance in the U. S. PatentNo. 323,856 of August 4:, 1885, and used for the manufacture ofbriquets, and the invention has for its object to provide a device forramming the material to be briqueted at the time when it is introducedinto the molds. This device increases the quantity of materialintroduced in each mold. Consequently, for a predetermined maximumpressure, the thickness of the briquets is augmented and a better yieldin weight is obtained.

In the annexed drawings: Figure 1 is an elevation view of a briquetingpress conforming with the invention. Fig. 2 is a side view. Fig. 3 is aplan view.

The machine comprises two opposing plungers 1 and 2 pivoted to beams 3and 4E oscillating on axes 6 and 7 respectively. These beams areoperated by the driving engine through any suitable transmissionmechanism.

The molds are located in a table 5 which receives from a suitable devicean intermittent rotary movement and come into position successively infront of the plungers 1 and 2 which in approaching one another producethe agglomeration of the material, and form it into briquets.

The material to be briqueted is supplied to the table from a vat 8,beneath which all the molds come successively into position and arefilled by the action of a blade or scraper 17 which receives from thedriving mechanism a continuous rotary movement. In the vat 8 are locatedtwo rammers 9 and 10 which are adapted to produce a preliminary rammingof the material. -These rammers are fixed to a slide 11 which can bedisplaced longitudinally on a guide 13. The slide 11 rests upon a fork18 pivoted to a cross-bar 14: which is operatively connected at 12 toone of the oscillating beams above mentioned and said slide ismaintained in cont-act with this fork by a spring 19 surrounding the rod20 which projects upwardly from said fork 18. The cross-bar 14 isconnected with the upper beam by means of shafts 21, 22 and links 15 and16. When the beam 3 is lowered it moves by the intermediary of links 15and 16, the cross-bar 14 and the fork 18, the spring 19 acts upon theslide 11 carrying the rammers which are thereby caused to descend intotwo molds in the table. The material to be briqueted is thus subjectedto two successive rammings before being submitted to the .doublecompression produced by the plungers 1 and 2. If for instance, the table5 turns in the direction of the arrow of Fig. 3, the material receivedby a mold is submitted to the action of the rammer 10. Asubsiding isthus produced and a new quantity of material is introduced in the moldby the blade 17. The

press embodying an oscillatory beam, amold-.

ing plunger carried and operated thereby, a molding table mounted forrotation and provided with a series of openings in which the saidplunger successively operates, of a means for charging the molding tablewith material to be formed into briquets, the means comprising a vatlocated over the table, a pair of rammers disposed in the vat andworking in unison, the rammers being arranged to simultaneously forcematerial into any two adjacent openings of the table, a slide carryingthe rammers, a rocking bar for causing raising and lowering movements ofthe slide, means for suitably associating the slide and the centralportion of the bar, and links connecting the opposite ends of the barand the said beam.

2. The combination with a briqueting press embodying an oscillatorybeam, amolding plunger carried and operated thereby, a molding tablemounted for rotation and provided with a series of openings in which thesaid plunger successively operates, of a. means for charging the moldingtable with material to be formed into briquets, the

means comprising a vat located over the table, a pair of rammersdisposed in the vat and working in unison, the rammers being arranged tosimultaneously force material into any two adjacent openings of thetable, a slide carrying the rammers, a. rocking bar for causing raisingand lowering movements of the slide, a fork pivoted at the center of therocking bar and upon which the slide rests, the fork having a stem whichprojects through the slide, an expansive coil spring surrounding thestem and bearing against the slide to hold the latter against the fork,and links connecting the opposite ends of the bar and said beam.

3. The combination with a briqueting press embodying an oscillatorybeam,- a molding plunger carried and operated thereby, a molding tablemounted for rotation and provided with a series of openings in which thesaid plunger successively operates, of a means for charging the moldingtable with material to be formed into briquets, the means comprising avat located over the table, a rammer disposed in the vat and beingvertically reciprocatory to successively charge the openings-in thetable with the material in the vat, a slide carrying the rammer andmeans for operating the rammer comprising a rocking bar which has itscentral portion pivotally associated with the slide, and linksconnecting the opposite ends of the bar and said beam.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
